This invention relates to locksfor guy strand guards.

Ordinarily, these guards are of sheet metal and are tubular or segmental in cross section, and various forms of locks are provided wires or cables used the guy strands, to support telephone or telegraph poles, or for similar purposes.

It is the primary purpose of the present invention to provide in simple, practical and emcient form, improved means for anchoring conven guy wire guards upon the guy tional forms of wires.

Another object is to provide a form of lock for mounting a guard upon a guy wire or cable, the locking element thereof having a cable-way device is e se out through one side or margin, whereated upon thecable or guy and including manually operable means for pressing the inserted guy strand against the innermost or closed purpose of effectually locking the device upon;

the strand.

Another object is an elongated end of the cable-way for the toprovidein a device oftheg character described, "a locking member having; cable-way opening out, through one margin thereof. and manually] operable means for pressing the inserted cablegto its seat longitudinally through said cable way and lockingly holding it in such position;

The said objects and purposes of [the invene tion as referred to may be accomplished through the agency of various specific,

upon certain generic principles common to the several specific jects and purposes in forms, and with the stated obview; as aforesaid, together with such incidental advantages as may appear,

attention is directed to the accompanying draw ings as exemplifying several. specific embodiments of my invention and wherein Figure 1 is a frontal elevation of a latch fingerform of cable lock constructed in accordance with my invention, the same guy wire guard, and locking-:

Figure 11 1 Figure 10. r I I a I As shown in Figures 1- to 5 inclusive,the-form of cable or guy wire lock therein represented I comprises a block A out through one margin of the block to form a cable-way: The block A is not of uniform =thickness, but is reducedeas shown at 3. atone-side of the able-way to form a centrally positioned web I I 3.0. a section on the line ;1;1- 11 of 4 disposed in parallelism with the faces of the 40 r block At its opposite or thicker side, they block A is bifurcated in the direction of the extended planeof the web whereby are formed two spaced] webs 5 at that side of the cable-way 2. These spaced webs 5 are then again pierced transversely 45 by elongated arcuate slots 6, extended substan tially, the length of the webs. An arcuate latch finger Tisloosely hinged at'oneend between the slotted webs 5 by means of a pin 8 passed trans-z versely through the end, the ends of the pin itself being loosely passed into the slots 16 at either side. 'Ke'eper'lugs 9 and 10 are rigidly mounted upon the two opposite faces of the web 4, cheer located further inward of the lugs as. 10 being the structure than the other lug 9, for apurpose having an opening 2 extended 35 to be later explained. The arrangement is such that the free end 11 of the latch finger 7 may be readily positioned at either side of the web 4 by merely sliding the pin.8 inwardly along the slots 6 to the position shown in dotted lines in Figure 2. In such position, the endll will be drawn in so as to clear the web 4 and may then be moved or swung to either side of the said web. The pin 8 may then be slid outwardly along the slots 6 and the end 11 of the latch finger 7 may be located upon the keeper lug at that side of the web 4.-

' I This formof lock may be used in connection with any conventional form of guard 12 and may be anchored to the guard in any desiredmanner, as

by cutting and turning outwardly. the flanged margins of the guards at eachrside of the block A, as shown at 13. A guard so prepared with a number of the blocks A mounted therein in spaced relation in conventional mannerfmay-be V or over a relatively, larger anchor rod 14ajeither of whichmay be set over a guy strand 14 passed into the cable-way 2, for this purpose the finger 7being withdrawn from its position across the cable-way. With the guy strand or anchor rod'properly located, the finger7 of each lock is moved outwardly along the slots 6 and the free or strand 14. The 45 end 11 is swung acrossthe cable-way and placed in engagement with one of the .keepers 9 or 10 uponthe web4, that keeper being selected which will cause the finger to bear with the requisite degree of pressure upon the strand 14 or rod 14a in order to firmly hold thetwo elements inlocked relation. Upon the larger anchor rod 14a,

the more outwardly located lug" 9 would probably be employed for latching the end 11 of the finger 7, whilef or the guy strand 14 of less diameter, the lug 10 would beutilized. It will thus be seen that the variouslyspace'd keeperlugs 9 and 10 in combination with the latch finger 7, afford handy means, for the accommodation ofwires or rods 'ofvarious diameters. A cable seat 15 may ing the edge of the'finger cutting into the cable be formed upon the finger 'Z-as means for preventcable-way 2, and a threaded bore 17 extended out through. the same to receive the usual set screw 18 for cooperating with the lock finger 7, there W being a registeringaperture 19 cut throughthe 7 guard at this point.

In the use of the lock described, it will be'noted that the pressure of thefingerfl upon the guy strand is exerted in a direction substantially lonf gitudinally inward of the cable-way 2, and so as to'- press the strand towards closed end 36 of the cable-way, thereby locking" and against the it firmly in place. I

In the assemblies represented in Figures 6 to 8 inclusive, the block B is of substantially uniform shown at. 23. I

thickness and is provided with a cable-way 2b similar to that of the block A, and whereby the blockB is partially divided, forming two branches or lobes 20. A pin or bolt socket 21 is formed in one of the lobes perpendicularly to the cablew'ay2b and having a mouth or opening 22 thereinto at a point somewhat out from the innerclosed end of the cable-way. At its outer end this socket opens out through the margin of the block, as Immediately back of its inner as-shownat 24, the same being so located as to stand positioned at the proposed lower side, of In the opposite lobe A 20 immediately across fromfand in axial alignment with the socket 21,.i's. formed a'keepersocket.

I t I conventional socket 16. may be formed in the block in alignment with the 25. A lock pin or bolt 26 is loosely mounted with in the socket 21, the inner end 27 of the pin being adapted to pass through the inner opening 22 of the socket and across into the keeper socket 25,

When mounted within a guard 12b, an aperture 30 is cut through the guard in alignment with the socket 2l, the saidaperture being less in diameter than the head of the pin 26, so that the latter may not fall'out through said aperture. The conventional structural features of set screw and socket, as indicated at 16, 1'7, 18 and 19 in Figures 1 and 2 of the first described form of lock, may be duplicated of course in the form shown in Figures 6, 7 andi8, as indicated at 16b, 17b, 18b,

and 19b. r

In the use of this lock, after it is seated over the'guy wire 14b as shown in Figure 6, the pin 26 being withdrawn, the assembly is turned ninety degr es in an anti-clockwise direction to the position shown in Figure 7, whereupon the pin 26 will fall partly through the openingf22, the end 27 will drop into the keeper socket 25, and the head 28 into the recess 24. The assembly may then be returned to its original position without dan-' ger of the pin 26 removing or becoming withdrawn from its locking position relative tofthe strand 141), because the head28 resting in the recess 24, prevents such action; If necessary, in order to facilitate placing the end '27 of the Spin within the socket 25, a pointed instrument such as a wire (not shown) may be inserted within the tool socket 29,'the said extended out through the aperture '30 provided in the guardr tapped bore25c.- The pin 260 is conical as shown and is provided with a kerf 31 for the 'accomm'odation of a screw driver (not shown) inserted through the aperture 300 of the guard'12c. With this arrangement, turning up the cone shaped pin 26c operates to force the cable 140 inwards against the closed end of thecable-way 2c, and in this operation, the resultant action of the conical pin 26 3 upon the strand 140 is substantially similar to the action of the latch' 7 upon the strand 14, as described and shown with referenceto the structures of Figures 1 to 5. I r w p 1 In the assembly represented in Figures 10 and 11, the block D is of uniform thickness and is formed with the cable-way 2d similar to the previously described structures. In this form, however, the'inner end of the cable-way is. slightly constricted or narrowed, assho'wn at 2d, and this.v

narrowed portion is then tappedandthreaded upon its margins as shown'at'32. A threaded plug 33 having a kerf 34 in its outer end, i s-provided for this threaded cable-way, andarotatable bearing 35 may also. be provided for the inner end of the plug if desired. This form 'of'lock is mounted withinthe guard 12d in manner'similar' In the use of this.

to the others above described. form, the screw plug. 33 is removed, and the guy strand 14d being properly seated within the cableway 2d, at the inner end thereof as shownini Figurev 10, the plug is then screwed-into place in; its threaded seat 32, thus pressing the strand14d wire serving as a handle;

A modification of the last described form is; shown in Figure 9. Herethe'keeper socket is a forcibly against the closedend 36d of the cableway 2d and looking it securely in place.

It is thought from the foregoing description that the use and operation of the several forms of locks will be fully understood. Any of the described forms may, of course, be anchored within the guards in the same manner as that pointed out in reference to the first described form represented in Figures 1 and 2, and as indicated by the analogous numbering of the corresponding parts and structural features, where such exist in the several forms. And, of course, any other means not shown may be employed for mounting the locks in place Within their guards. Moreover, while certain forms and shapes of guards are here shown in connection with the description of my invention, and the locks themselves are represented as conforming to such shapes, it is understood that by proper modification and adaptation, either of the several forms of my invention might or could be used upon guards of other shapes or forms, as might be desired, and while I have herein described and shown certain assemw blies of elements and structural features as more prominently characterizing my invention, it is understood that I may vary and modify the said elements and structural features, in details and matters not departing from the spirit of my invention, as defined in the appended claims.
